Transmission, Europe

Artemis I

A 900 MW offshore converter station through a partnership with the Dutch company TenneT for the CI Artemis K/S fund.

Through a partnership with TenneT (the Dutch Transmission System Operator), CI Artemis K/S (the second fund managed by Copenhagen Infrastructure Partners) has invested in the offshore transmission (HVDC) platform, Dolwin3, offering a regulated return set by the German Government. The project has a total CAPEX of EUR 1,9bn, of which Copenhagen Infrastructure I is funding EUR ~385m through equity.

The Dolwin3 project is the eighth offshore transmission platform that TenneT is constructing in the German North Sea and involves the construction of a 900 MW DC grid connection for wind farms in the south-western part of the German North Sea. The DolWin3 project is the third connection in the DolWin cluster. The distance from the wind farms to the coast is about 83 kilometres. The grid connection runs for another 79 kilometres on land to the converter station at Dörpen West, which will serve as the onshore electricity grid coupling point.
